21.High school is regarded as the best time of my life. Beside (1)
classes and homework, there has something more that I especially (2)
treasure. In order to leave the school with no regrets, I'll make use (3)
of my limit time to review the lessons I've learned. Meanwhile, I'd (4)
like to show my gratitude to all the teachers who has given me so (5)
much help in the past three years. In addition, this is necessary for (6)
me to have a talk with who might have misunderstood me, for I do (7)
care about the friendship between us. For the purpose of improving (8)
myself, I'll ask my classmates some advice which may be of great (9)
value to me. With these thing done, I will have no regrets in my (10)
high school life.
